The holder is fine, but the navigation is on specialized devices much better!

The support I have attached without much effort on the handlebars of my mountain, my first experiences are very positive. The parts of the holder are stable, the iPhone 6 Plus is also housed at fast driving on gravel roads safe, especially if you stretched the rubber band about. You have to have no fear that it falls out. However, I must before pinching the sleeve, in which I usually aufbewahre my iPhone, lose weight before.
After securing the support I have the app on the iPhone komoot installed. And as a buyer of the holder obtains a code with which you can select a region otherwise paid card and charge for free. This is a very pleasing amenity. And the card can be used offline even so the frequent dead spots, on the one mainly encounters in the mountains, the navigation does not interrupt. Through the ball joint of the holder, the iPhone can always align it so that you have a good view of the display. In short: I am very pleased by the support.
The large display of the iPhone 6 Plus is of course very beneficial in the pursuit of a route. But functional is a specialized unit such. As the Garmin Edge 810 that I use else for bicycle navigation, clearly superior. But this has nothing to do with the bracket.
